EMISSION DATA
EMISSION CONTROL
(EXHAUST and EVAPORATIVE)
EPA 2010 and Later and/or C.A.R.B. TIER III
The emission control system for the engine is EM
(engine modifi cation) and, if the second to last
character of the Engine Family on the Emission
Control Information label (sample below) is "C", "K",
or"T", the emission control system is EM and TWC
(3-way catalyst). The fuel tank/fuel line emission
control system is EVAP (evaporative emissions).
Evaporative emissions for California models may
only be applicable to fuel tanks.
An Emission Control Label is located on the
engine. (This is an example only, information on
label varies by engine family).
PRODUCT EMISSION DURABILITY
(EMISSION COMPLIANCE PERIOD)
The 300 hours emission compliance period is
the time span selected by the manufacturer
certifying the engine emissions output meets
applicable emissions regulations, provided that
approved maintenance procedures are followed
as listed in the Maintenance Section of this
manual.
